Application filed. September 24, 1909; Serial No. 519,471.

To'alZ whom it may concern:

Be it known that 1, Human P. MURPHY, a citizen of the United States, andresident of St. Louis, State of Missouri, have invented a releaserigging that is practical and can be applied to cabooses, tenders, etc.,thathave no dcadwoods, as well as to cars w1th deadwoods; and with thisand minor objectsin view my invention consists of the parts andcombination of parts as will be more fully hereinafter set out.

In the drawing, Figure l is a top plan view of a car end sill andcoupler, parts being broken away, with my improved rigging in position;Fig. 2 is a front elevation of the same; Fig. 3 is a detail view of thepin op erating lever and its mounting; Fig. 4 is a front elevation withthe locking pin and locking pin lever in elevated position and the handlever in normal position; Figs. 5

= and 6 are detail views showing different bends in the inner end of thehand lever.

represents the end sill of a car which may be of any approved patternand may or may not have a deadwood, as far as the practicability of myinvention is concerned.

- 2 are suitable bearings secured in any suitable manner to the endsill, in which is loosely journaled the hand operated rod or lever 3,the outer end of which terminates in a handle 4, which extends below theunderface of the end sill as shown in Fig. 2. The inner end of the lever3 terminates in a crank 5 extending horizontally when the lever 3 is inoperative position on the end sill and is at a right. angle to thehandle 4. 6 is an eye formed on the extreme end of the crank 5, the bodyforming the eye,,being formed in the longitudinal'axls of'the.

crank while the opening therethrough extends inthe vertical ortransverse axis.

The pin operating lever 7 is tapered along its main body toward itsinner end to adapt it to pass through the eye 8 of the usual lockin pinand is of such diameter that the eye 8 may slide freely thereon withminimum friction. The extreme inner end .of the lever 7 is bent to forma hook 9, which prevents the lever from becoming accidentally disengagedfrom the eye 8. The outer end of the pin lifting lever is bent to form ashoulder 11 and still further bent to form a hook Specification ofLetters Patent.

12, by means of which'the pin lever 7 is secured to the crank 5 byreason of its ongagement with the eye 6; the engagement of one side ofthe hook 12 with the shoulder 11 and the engagement of the hook 12 withthe other side of the eye serves to hold or support the pin lever 7 in ahorizontal position normally, as shown in Fig. 2. The two levers may beentirely of'commercial bar wrought iron, which is a materialconsideration from the standpoint of durability and manufacture. Thisimproved release rigging allows the coupler to move in and out sidewiseand yet after the locking pin has been raised for lock setting, thehandle 4 will drop to its normal vertical position,

while the pin lifting lever remains elevatedwith the pin.

The rod or lever 8 is revolved by means of the handle, which in turnelevates the crank 5, which through the hook 10 and eyefi elevates thepin'lifting lever 7, thereby lifting the locking pin for lock setting orthrowing open the knuckle full open. As soon is the operator releasesthe handle 4-, the rod or.

lever 3 revolves under the weight of the handle, whereby the handle willdrop and assume its normal" ver ical position against the face of theend sil thus eliminating all danger and damage resulting from the EIS Ehandle being struck by an abutting car.

The joint formed by the eye 6 and hook 12 is, for all practicalpurposes, substantially a universal jointwhich permits the lever 7toremain in its elevated position, while the locking pin isheld 1n 1tselevated position rigging; may be used on cabooses that must beuncoupled by a chain to hand rail and yet comply with the safetyappliance law by being operative outside the rails.

The pin lever 7 is free to move backward,

forward and upward independent of any for lock setting, eta, and at thesame time permits the handle4 to return to and re final 11 111 itsnormal vertical position. This lever 3. In Fig. 5, the bend is at aright angle to the main body of the lever. .In this construction, theouter end of the pin lever shown in dotted lines is formed in an eye,

shown in section. Should the draw bar pull a joint which will permit thecrank to return to normal position after operating the pin lever withoutmoving the pin lifting lever from its abnormal position.

Copies of this patent may be obtained for five cents each, by addressingthe 60 Washington, D. 0.

2. A release rigging including a hand operated lever having a dependinghandle at its outer end and a forwardly extending crank at its innerend, the'crank havin Ian eye formed at its inner end, a pin li tin leverhaving an open hook at its outer end to engage the eye of the saidcrank, whereby .the pin lifting lever may be elevated, and

remain in such'elevated position while the crank and handle of the handlever are free to return to their normal position.

In testimony whereof I afiix my signature in presence of two witnesses.
